I think that we should add aircraft collision on the advanced server, so if people hit each other they will have to reset to parking. This adds more realism to the simulator, because in real life you can’t ride through other planes. This would also make people play more seriously.
Another request is that when someone chooses a parking space, that parking space should either come as"booked" or “occupied” until the person leaves, or you can install a time limit like maybe 2 minutes until it shows the parking slot as free. This also adds realism as in real live you never have 2 aircraft in each other at the same gate.
